Yep, that is a problem. Just stop walking into walls. However, metro is one game I have it switched off for turning up the eyecandy instead.
I have a la pavoni 2a, great bit of kit. Not failed since I got it. Highly recommended. I think it's been rebranded to the europiccola - el now.
Hmmm, I don't think I am skilled enough to be pulling shots with a hand operated machine

A point about metro for those having problems. Before the 10.7 drivers, I was unable to launch the game at all in DX11 mode at 5760x1080, but since installing I can run in DX11 with 4xAA + AAA + No Tessellation.
